Abstract:
Objective To study reaction principle of bilirubin vanadate oxidation method and bilirubin oxidase method through comparison of the determination results,and discuss similarities and difference between the two methods .Methods 310 ca-ses were measured and analyzed with each method.Abnormal samples were further investigated.Results Fortotal bilirubin, the regression equation obtained wasY=1.065 1X+1.197 2,the correlation coefficientr=0.997 0.For direct bilirubin of a-dults and children greater than 30 days,the regression equation wasY=0.945 9X+0.599 5 and the correlation coefficient r=0.994 4.For neonatal direct bilirubin,the regression equation wasY=0.410 4X+2.756 3 and the correlation coefficient r=0.883 5.The results from vanadate oxidation method were unacceptable for abnormal neonatal serum measurement after serial dilution.Conclusion The overall conclusions were that for the measurement of total bilirubin,and direct bilirubin for adults and children older than 30 days.The correlation between these two methods is in an acceptable range,for measure-ment of neonatal direct bilirubin,the correlation between thesetwo methods was not acceptable.It is not recommended to measure neonatal direct bilirubin by vanadate oxidation method.
